Relationships between 22 unique comorbidities and idiopathic pulmonary fibrosis (IPF) were assessed by a bidirectional Mendelian randomization (MR) approach in a retrospective study. Three of the comorbidities that were examined appeared causally associated with an increased risk of IPF.

Researchers used summary statistics of large-scale genomewide association studies (GWAS) obtained from the IPF Genetics Consortium. For replication, they used data from the Global Biobank Meta-Analysis Initiative.

Pulmonary or extrapulmonary illnesses are regularly observed to be comorbidities associated with IPF. Although randomized control trials can provide strong deductive evidence of causal relationships between diseases, they are also often subject to inherent practical and ethical limitations. MR is an alternative approach that exploits genetic variants of genes with known function as a means to infer a causal effect of a modifiable exposure on disease and minimizes possible confounding issues from unrelated environmental factors and reverse causation. Bidirectional MR extends the exposure-outcome association analysis of MR to both directions, producing a higher level of evidence for causality, Jiahao Zhu, of the Department of Epidemiology and Health Statistics, Hangzhou, China, and colleagues wrote.
 

Study details

In a study published in the journal Chest, the researchers reported on direction and causal associations between IPF and comorbidities, as determined by bidirectional MR analysis of GWAS summary statistics from five studies included in the IPF Genetics Consortium (4,125 patients and 20,464 control participants). For replication, they extracted IPF GWAS summary statistics from the nine biobanks from the GBMI (6,257 patients and 947,616 control participants). All individuals were of European ancestry.

The 22 comorbidities examined for a relationship to IPF were identified through a combination of a PubMed database literature search limited to English-language articles concerning IPF as either an exposure or an outcome and having an available full GWAS summary statistic. The number of patients in these studies ranged from a minimum of 3,203 for osteoporosis to a maximum of 246,363 for major depressive disorder.

To estimate causal relationships, single-nucleotide polymorphism selection for IPF and each comorbidity genetic instrument were based on a genomewide significance value (P < 5x10^–8) and were clumped by linkage disequilibrium (r² < 0.001 within a 10,000 kB clumping distance). Evidence from analysis associating each comorbidity with IPF was categorized as either convincing, suggestive, or weak. Follow-up studies examined the causal effects of measured lung and thyroid variables on IPF and IPF effects on blood pressure variables.
 

Convincing evidence

The bidirectional MR and follow-up analysis revealed “convincing evidence” of causal relationships between IPF and 2 of the evaluated 22 comorbidities. A higher risk of IPF was associated with gastroesophageal reflux disease (GERD). Importantly, a multivariable MR analysis conditioning for smoking continued to show the causal linkage between GERD and a higher risk of IPF. In contrast, the genetic liability of COPD appeared to confer a protective role, as indicated by an associated decrease in risk for IPF. The researchers suggest that this negative relationship may be caused by their distinct genetic architecture.

Suggestive evidence

“Suggestive evidence” of underlying relationships between IPF and lung cancer or blood pressure phenotype comorbidities was also found with this study. The MR results give support to existing evidence that IPF has a causal effect for a higher lung cancer risk. In contrast, IPF appeared to have a protective effect on hypertension and BP phenotypes. This contrasted with VTE: On the basis of bidirectional MR analysis, the researchers suggest that VTE was more likely to be a cause rather than a consequence of IPF. Evidence suggestive that genetic liability to hypothyroidism could lead to IPF was also found (International IPF Genetics Consortium, P < .040; MR PRESSO method; and GBMI, P < .002; IVW method).

Limitations

The primary strengths of the study was the ability of MR design to enhance causal inference, particularly when large cohorts for perspective investigations would be inherently difficult to obtain. Several noted limitations include the fact that causal estimates may not be well matched to observational or interventional studies and there was a low number of single-nucleotide polymorphisms available as genetic instruments for some diseases. In addition, there was a potential bias because of some sample overlap among the utilized databases, and it is unknown whether the results are applicable to ethnicities other than those of European ancestry.

Conclusion

Overall, this study showed that a bidirectional MR analysis approach could leverage genetic information from large databases to reveal causative associations between IPF and several different comorbidities. This included an apparent causal relationship of GERD, venous thromboembolism, and hypothyroidism with IPF, according to the researchers. These provide the basis to obtain “a deeper understanding of the pathways underlying these diverse associations” that may have valuable “implications for enhanced prevention and treatment strategies for comorbidities.”

The patient’s recurrent indurated nodules under her arms and other intertriginous areas, often draining pus, are consistent with a diagnosis of hidradenitis suppurativa (HS).

HS is a chronic inflammatory and suppurative skin condition that primarily involves the sweat glands.¹ The most commonly affected sites are intertriginous areas that include the axillae, groin, and perianal and inframammary regions.² Prevalence of this disorder ranges from 0.05% to 4.1% of the population with an onset from puberty to adulthood, usually at around 40 years of age.³ Its incidence is twice as high in women as men and is more common in Black individuals.^4,5

While its pathogenesis is not fully understood, it’s believed that excess proliferation of keratinocytes contributes to occlusion, leading to plugging of hair follicle ducts. Hormones, smoking, and obesity may contribute to and exacerbate HS. Intertriginous areas are prone to friction, leading to inflammation and further clogging.

The inflammation evolves into a chronic foreign body-type granulomatous inflammation with the potential for rupture, tunneling, and draining sinuses, which, although malodorous, are sterile, separating HS from an infected abscess.⁵ The result is thick, dense, scarred tissue.

The diagnosis is clinical in nature, with the history and physical exam distinguishing it from other skin disorders. In addition to the recurring physical pain, there is the emotional distress and self-consciousness about the drainage, odor, and scarring. This particular patient said that she avoided wearing sleeveless shirts due to the lesions’ appearance.

Treatment is multifactorial. Smoking and obesity are contributory factors, so smoking cessation and weight loss are recommended. For very mild HS, topical clindamycin 1% twice daily may suffice, but usually, due to the amount of inflammation, oral antibiotics are the initial therapy. (The use of antibiotics is for their anti-inflammatory component, as the nodules and unruptured tracts are sterile.)

Doxycycline 100 mg twice daily is the usual starting systemic antibiotic. In more severe or resistant cases, a combination of clindamycin and rifampin 300 mg each twice daily is used. (Worth noting: Rifampin interacts with oral contraceptives and many of these patients are women of reproductive age.) Treatment length is usually long (10 to 12 weeks) and recurrence is common.³

Spironolactone 100 mg daily and metformin 1000 mg extended release daily, which reduces insulin resistance, may be helpful. Intralesional injections of 10 mg/mL of triamcinolone in sterile saline can relieve the painful inflamed tracts. Referral for biologic agents, including infliximab, may be needed in severe cases that do not respond to other measures. Although invasive, wide debridement of the diseased tissue can reduce the disease burden.⁶

This particular patient said that she’d stopped smoking 3 years earlier and would work on losing weight. She was prescribed topical clindamycin 1% lotion twice daily along with oral clindamycin and rifampin dosed as above for 3 months. She declined metformin and intralesional injections. At a follow-up appointment 3 weeks later, she was pleased with the decrease in inflammation and had only 1 remaining tender area of fluctuance. She again declined injections and planned to continue on her oral and topical antibiotics.

Biopsy revealed a lichenoid infiltrate in the upper dermis with thinning of the epidermis and a predominance of plasma cells. This finding, along with a red-orange, glossy lesion on the glans penis in an uncircumcised man is a classic presentation of Zoon balanitis.

Zoon balanitis is a chronic, idiopathic disorder that affects uncircumcised men who are middle-aged and older.¹ Although the exact pathogenesis is unknown, it is hypothesized to be the result of chronic irritation due to poor hygiene/urine retention with prepuce dysfunction. The classic clinical presentation is an asymptomatic, well-defined, orange-to-red glazed patch with symmetric small red “cayenne pepper” spots contained within the glans penis and/or prepuce. Often there are symmetric “kissing lesions” where a second lesion of similar morphology is apparent on the prepuce where it meets the glans penis. While this disorder is typically asymptomatic, it can be associated with itching and/or burning.

There are several other inflammatory disorders in the differential for Zoon balanitis (erosive lichen planus, lichen sclerosus, psoriasis), but the most important consideration is penile intraepithelial carcinoma, specifically erythroplasia of Queyrat. Erythroplasia of Queyrat can be difficult to distinguish clinically and often requires a biopsy. Zoon balanitis will show a plasma cell predominant lichenoid infiltrate, whereas erythroplasia of Queyrat will show squamous cell carcinoma in situ.

It is important to note that Zoon balanitis is a clinicopathologic diagnosis and that zoonoid inflammation on biopsy is not pathognomonic, as this can also be seen in other inflammatory and neoplastic conditions. It is, therefore, advisable to follow up with patients with Zoon balanitis to ensure that the lesion is resolving and/or not getting worse.

Improved hygiene measures are the mainstay of treatment; circumcision is also effective.² Both can help keep the glans clean and dry. In those with symptomatic disease, low-strength topical steroids including 1% hydrocortisone ointment or cream twice daily or topical calcineurin inhibitors (pimecrolimus 1% or tacrolimus 0.1%) twice daily can be used for symptom management.

Because this patient’s disease was asymptomatic, treatment was deferred. He was counseled to draw back the foreskin when urinating and to do the same while showering so that he could wash, then dry, the glans before returning the foreskin to its normal position. The patient is being monitored clinically.

Semaglutide didn’t significantly improve liver fibrosis or achieve resolution of nonalcoholic steatohepatitis (NASH)–related compensated cirrhosis, compared with placebo, according to a phase 2 trial.

However, the glucagonlike peptide–1 (GLP-1) receptor agonist led to improvements in liver enzymes, liver steatosis, weight, triglycerides, and very low-density lipoprotein (VLDL) cholesterol. Similar proportions of patients in each group reported adverse events, such as nausea, diarrhea, and vomiting.

“Previous studies in patients with NASH and stage 2 or 3 fibrosis have shown that semaglutide can improve NASH resolution over 72 weeks. However, there are limited data on whether any therapy is effective in patients with NASH cirrhosis,” lead author Rohit Loomba, MD, founding director of the NAFLD Research Center at the University of California, San Diego, said in an interview.

“Although semaglutide did not succeed in improving histological fibrosis, it had success in improving other clinically important parameters, such as cardiometabolic risk factors, liver enzymes, liver fat, and noninvasive biomarkers of fibrosis,” he said.

The study was published online  in The Lancet Gastroenterology & Hepatology.
 

Analyzing safety and efficacy

Dr. Loomba and colleagues conducted a double-blind, placebo-controlled phase 2 trial that enrolled 71 patients at 38 centers in the United States and Europe between June 2019 and April 2021. Adults with biopsy-confirmed NASH-related cirrhosis and a body mass index (BMI) of at least 27 kg/m² were randomly assigned 2:1 to receive either once-weekly subcutaneous semaglutide at 2.4 mg or a visually matching placebo.

Patients were randomly allocated through an interactive web system, which stratified participants on the basis of the presence or absence of type 2 diabetes. Patients, investigators, and outcomes analysts were masked to the treatment assignment.

The primary endpoint was the proportion of patients with an improvement in liver fibrosis of one stage or more without a worsening of NASH after 48 weeks, which was measured through biopsy in the intention-to-treat population. Safety was also assessed in all patients who received at least one dose of semaglutide.

Among the 71 patients, 47 were randomly assigned to the semaglutide group and 24 to the placebo group. About 90% completed treatment, and 63 had evaluable paired biopsies for primary endpoint assessment.

Between the groups, 49 participants (69%) were women and 22 were men. The average age was 59.5 years, and the average BMI was 34.9. About 75% of patients had diabetes at baseline, with an average hemoglobin A1c of 7.1%.

After 48 weeks, researchers found no statistically significant difference between the groups in the proportion of patients with an improvement in liver fibrosis of one stage or more without worsening of NASH. In the semaglutide group, five patients (11%) had an improvement, compared with seven patients (29%) in the placebo group (odds ratio, 0.28; 95% confidence interval, 0.06-1.24, P = .087).

There also wasn’t a significant difference between groups in the proportion of patients who achieved NASH resolution. In the semaglutide group, 16 patients (34%) had resolution, compared with 5 patients (21%) in the placebo group (OR, 1.97; 95% CI, 0.56-7.91; P = .29).

In addition, a lower proportion of patients achieved both NASH resolution and improvement in liver fibrosis with semaglutide versus placebo, although the difference wasn’t significant. In the semaglutide group, three patients (6%) achieved both, compared with three patients (13%) in the placebo group (OR, 0.48; 95% CI, 0.06-3.91; P = .4). A lower proportion of patients had an improvement in liver fibrosis stage with semaglutide versus placebo.
 

Some improvements seen

However, the semaglutide group had significantly greater improvements in liver steatosis (but not stiffness), liver fat volume, procollagen 3 peptide, and liver enzymes such as ALT, AST, and gamma-glutamyltransferase.

Body weight decreased by 8.83% in the semaglutide group, compared with 0.09% in the placebo group, which was a significant difference. BMI, waist circumference, triglycerides, and VLDL cholesterol were also significantly lower in the semaglutide group, but total cholesterol and blood pressure measurements weren’t significantly different. Among those with type 2 diabetes, A1c also decreased in the semaglutide group but did not in the placebo group.

Similar proportions of patients in each group reported adverse events. In the semaglutide group, 42 patients (89%) had an adverse event, compared with 19 patients (79%) in the placebo group. In addition, six patients (13%) in the semaglutide group and two patients (8%) in the placebo group reported serious adverse events.

The most common adverse events in the semaglutide and placebo groups were nausea (45% and 17%), diarrhea (19% and 8%), and vomiting (17% and none), which mainly occurred during treatment initiation or dose escalation. No patients withdrew from the trial because of adverse events, although five had a dose reduction. Hepatic and renal function remained stable after semaglutide treatment, and there were no decompensating events or deaths.

“GLP-1 analogue exposure – among patients with compensated cirrhosis who suffer from morbid obesity and type 2 diabetes – for the treatment of diabetes appears to be well-tolerated and may be safe,” Dr. Loomba said. “Further studies are needed in this study population.”
 

Considering next steps

Dr. Loomba and colleagues are continuing research around risk factors linked to advanced fibrosis, such as type 2 diabetes, a family history of cirrhosis, and the presence of key genetic risk alleles. Gut dysbiosis also appears to increase the risk for advanced fatty liver disease, he said.

Future clinical trials could focus on therapeutic options for patients with advanced fibrosis, particularly those with cirrhosis who face increased risks for liver-related complications and mortality.

“As these patients are oftentimes excluded from initial randomized controlled trials, we have significantly less information on how to address obesity, type 2 diabetes, and NASH in these patients,” Fernando Bril, MD, a physician-scientist focused on NASH-related research at the University of Alabama at Birmingham, said in an interview.

Dr. Bril, who wasn’t involved with this study, wrote an accompanying editorial in The Lancet Gastroenterology & Hepatology.

Patients with NASH-related cirrhosis may have progressed to a point of the disease where fibrosis regression may be more difficult to achieve, he said.

“This emphasizes that early diagnosis of patients with NASH is crucial,” he said.

“Therefore, primary care providers, endocrinologists, and diabetologists need to have a low threshold to suspect liver disease in patients with overweight, obesity, and/or type 2 diabetes. Only this will allow for early initiation of therapy, which may delay the progression of liver disease.”

In further research, investigators may want to consider the lack of NASH resolution, a result that could be caused by this study being underpowered, Dr. Bril noted. The trend in resolution in this study appeared similar to improvements seen in NASH patients without cirrhosis in other studies, he said. The weight reduction and improved diabetes control in this group also shows promise.

“While a purist may be adamant that this was a negative study for histological outcomes, it is essential to take note of the positive results in many secondary outcomes,” he said. “Improving cardiometabolic risk in these patients is essential because many still die of cardiovascular disease and not liver-related complications.”

At the same time, it’s important to note that NASH can’t be oversimplified as “a matter of weight,” Dr. Bril said. Significant weight loss in the study didn’t result in histologic improvement, which means other strategies are needed to treat the disease.

“Negative results from this study emphasize that monotherapy may not be enough to improve NASH and liver fibrosis,” he said. “In a similar way we treat type 2 diabetes and hypertension with combination therapy, we need to consider a similar approach for patients with NASH.”

The study was sponsored by Novo Nordisk, which manufactures semaglutide. The authors declared grant funding, speaker fees, and consultant roles with numerous pharmaceutical companies. Dr. Bril had no relevant disclosures.

Semaglutide didn’t significantly improve liver fibrosis or achieve resolution of nonalcoholic steatohepatitis (NASH)–related compensated cirrhosis, compared with placebo, according to a phase 2 trial.

However, the glucagonlike peptide–1 (GLP-1) receptor agonist led to improvements in liver enzymes, liver steatosis, weight, triglycerides, and very low-density lipoprotein (VLDL) cholesterol. Similar proportions of patients in each group reported adverse events, such as nausea, diarrhea, and vomiting.

“Previous studies in patients with NASH and stage 2 or 3 fibrosis have shown that semaglutide can improve NASH resolution over 72 weeks. However, there are limited data on whether any therapy is effective in patients with NASH cirrhosis,” lead author Rohit Loomba, MD, founding director of the NAFLD Research Center at the University of California, San Diego, said in an interview.

“Although semaglutide did not succeed in improving histological fibrosis, it had success in improving other clinically important parameters, such as cardiometabolic risk factors, liver enzymes, liver fat, and noninvasive biomarkers of fibrosis,” he said.

The study was published online  in The Lancet Gastroenterology & Hepatology.
 

Analyzing safety and efficacy

Dr. Loomba and colleagues conducted a double-blind, placebo-controlled phase 2 trial that enrolled 71 patients at 38 centers in the United States and Europe between June 2019 and April 2021. Adults with biopsy-confirmed NASH-related cirrhosis and a body mass index (BMI) of at least 27 kg/m² were randomly assigned 2:1 to receive either once-weekly subcutaneous semaglutide at 2.4 mg or a visually matching placebo.

Patients were randomly allocated through an interactive web system, which stratified participants on the basis of the presence or absence of type 2 diabetes. Patients, investigators, and outcomes analysts were masked to the treatment assignment.

The primary endpoint was the proportion of patients with an improvement in liver fibrosis of one stage or more without a worsening of NASH after 48 weeks, which was measured through biopsy in the intention-to-treat population. Safety was also assessed in all patients who received at least one dose of semaglutide.

Among the 71 patients, 47 were randomly assigned to the semaglutide group and 24 to the placebo group. About 90% completed treatment, and 63 had evaluable paired biopsies for primary endpoint assessment.

Stereotactic body radiation therapy (SBRT) and surgery offer nearly equal overall survival rates for patients with stage I and II non–small cell lung cancer (NSCLC), according to population-based data from a German cancer registry.

“From a public health perspective, SBRT is a good therapeutic option in terms of survival, especially for elderly and inoperable patients,” noted the study authors, led by Jörg Andreas Müller, MD, department of radiation oncology, University Hospital of Halle, Germany.

The analysis was published online in the journal Strahlentherapie Und Onkologie.

Surgery remains the standard of care for early stage NSCLC. However, many patients are not eligible for surgery because of the tumor’s location, age, frailty, or comorbidities.

Before the introduction of SBRT, conventional radiation therapy was the only reasonable option for inoperable patients, with study data showing only a small survival improvement in treated vs. untreated patients.

High-precision, image-guided SBRT offers better tumor control with limited toxicity. And while many radiation oncology centers in Germany adopted SBRT as an alternative treatment for surgery after 2000, few population-based studies evaluating SBRT’s impact on overall survival exist.

Using the German clinical cancer registry of Berlin-Brandenburg, Dr. Müller and colleagues assessed SBRT as an alternative to surgery in 558 patients with stage I and II NSCLC, diagnosed between 2000 and 2015.

More patients received surgery than SBRT (74% vs. 26%). Those who received SBRT were younger than those in the surgery group and had better Karnofsky performance status.

Among patients in the SBRT group, median survival was 19 months overall and 27 months in patients over age 75. In the surgery group, median survival was 22 months overall and 24 months in those over 75.

In a univariate survival model of a propensity-matched sample of 292 patients – half of whom received SBRT – survival rates were similar among those who underwent SBRT versus surgery (hazard ratio [HR], 1.2; P = .2).

Survival was also similar in the two treatment groups in a T1 subanalysis (HR, 1.12; P = .7) as well as in patients over age 75 (HR, 0.86; P = .5).

Better performance status scores were associated with improved survival, and higher histological grades and TNM stages were linked to higher mortality risk. The availability of histological data did not have a significant impact on survival outcomes.

Overall, the findings suggest that SBRT and surgery offer comparable survival outcomes in early stage NSCLC and “the availability of histological data might not be decisive for treatment planning,” Dr. Müller and colleagues said. 

Drew Moghanaki, MD, chief of the thoracic oncology service at UCLA Health Jonsson Comprehensive Cancer Center, Los Angeles, highlighted the findings on Twitter.

A thoracic surgeon from Germany responded with several concerns about the study, including the use of statistics with univariate modeling and undiagnosed lymph node (N) status.

Dr. Moghanaki replied that these “concerns summarize how we USED to think. It increasingly seems they aren’t as important as our teachers once thought they were.  As we move into the future we need to reassess the data that supported these recommendations as they seem more academic than patient centered.”

The study authors reported no specific funding, and no relevant financial relationships.

A mindfulness-based cognitive therapy self-help (MBCT-SH) intervention in which patients were supported by a trained practitioner led to better clinical outcomes at lower cost than practitioner-supported cognitive-behavioral therapy self-help (CBT-SH), new research shows.

The findings suggest that “offering practitioner-supported MBCT-SH as an intervention for mild to moderate depression would improve outcomes and save money compared with practitioner-supported CBT-SH,” noted the investigators, led by Clara Strauss, PhD, DClinPsy, with the University of Sussex School of Psychology in England.

Practitioner-supported CBT-SH is recommended in U.K. national treatment guidelines for mild to moderate depression. However, some patients’ conditions don’t respond, and dropout rates are high.

The Low-Intensity Guided Help Through Mindfulness (LIGHTMind) trial tested practitioner-supported MBCT-SH as an alternative.

The findings have “important implications” for the more than 100,000 people currently offered CBT-SH for depression in the Improving Access to Psychological Therapies (IAPT) program each year and in publicly funded services elsewhere, the researchers noted.

If translated into routine practice, “this would see many more people recovering from depression while costing health services less money,” they added.

The study was published online in JAMA Psychiatry .
 

Practice changing?

The trial included 410 adults (mean age, 32 years; 62% women) with mild to moderate depression who were recruited from 10 publicly funded psychological therapy services in England as part of the IAPT program.

Participants were given one of two established self-help workbooks – The Mindful Way Workbook: An 8-Week Program to Free Yourself from Depression and Emotional Distress, written by the pioneers of MBCT, or Overcoming Depression and Low Mood, 3rd Edition: A Five Areas Approach, which is a CBT-SH program widely used in IAPT.

Use of the self-help books was supported by six structured phone or in-person sessions with a trained psychological well-being practitioner.

The primary outcome was depression symptom severity at 16 weeks, which was determined on the basis of Patient Health Questionnaire 9 (PHQ-9) score.

At 16 weeks following randomization, MBCT-SH led to significantly greater reductions in depression symptom severity compared with CBT-SH (mean PHQ-9 score, 7.2 vs. 8.6; between-group difference, 1.5 points; P = .009; d = −0.36).

MBCT-SH also had superior effects on anxiety symptom severity at 16 weeks.

At the 42-week follow-up, between-group effects on depression and anxiety symptom severity remained in the hypothesized direction but were nonsignificant.

This could be due in part by the greater postintervention psychological therapy accessed by participants in the CBT-SH group, the investigators noted.

Practitioner-supported MBCT-SH was more cost-effective than supported CBT-SH.

On average, the CBT-SH intervention cost health services £526 ($631) more per participant than the MBCT-SH intervention over the 42-week follow-up. The probability of MBCT-SH being cost-effective compared with CBT-SH exceeded 95%, the researchers noted.
 

Useful model for the United States

Commenting for this news organization, Zindel Segal, PhD, professor of psychology, University of Toronto, Scarborough, cautioned against making too much of the differences between the groups, because CBT-SH “trended positive and had a pretty healthy effect size, it just never reached significance.

“I wouldn’t say mindfulness drastically outperformed cognitive therapy. But cognitive therapy is a robust treatment in its own right, and so doing a little bit better is significant,” Dr. Segal said.

He also noted that, appropriately, the trial enrolled adults who were experiencing moderate depression and were not acutely ill. “That’s one of the rationales for self-help compared to providing patients with a more resource-intensive group treatment.

“If you look at the needs of people with moderate depression, what you find is that for cognitive therapy to work, negative thoughts and feelings need to be pervasive in order to make use of the techniques,” Dr. Segal explained.

“With mindfulness, you don’t need any to have constant negative thoughts or feelings. Anything that arises in your experience serves as grist for mill in terms of concentration and focus,” Dr. Segal said.

He also noted that mindfulness-based intervention is “more optimized” for people who are experiencing some measure of recovery or remission.

“It’s well suited for that, as it trends towards the wellness spectrum. But for people who might have greater levels of acuity or severity, cognitive-behavioral therapy might be indicated,” said Dr. Segal.

He also said the U.K. study findings are relevant to U.S. patients with depression.

“While it’s not disseminated in the same way through any kind of national program, the self-help books that are used are widely available, and the support that people were offered, either in person, telephone, or email, could be easily delivered. This would be a very useful model,” Dr. Segal said.

The LIGHTMind trial was funded by the National Institute for Health and Care Research and the Brighton and Sussex Clinical Trials Unit. Dr. Strauss has received grants from Headspace, is research lead for Sussex Mindfulness Centre, and has been chief investigator on National Institute for Health and Care Research.

A mindfulness-based cognitive therapy self-help (MBCT-SH) intervention in which patients were supported by a trained practitioner led to better clinical outcomes at lower cost than practitioner-supported cognitive-behavioral therapy self-help (CBT-SH), new research shows.

The findings suggest that “offering practitioner-supported MBCT-SH as an intervention for mild to moderate depression would improve outcomes and save money compared with practitioner-supported CBT-SH,” noted the investigators, led by Clara Strauss, PhD, DClinPsy, with the University of Sussex School of Psychology in England.

Practitioner-supported CBT-SH is recommended in U.K. national treatment guidelines for mild to moderate depression. However, some patients’ conditions don’t respond, and dropout rates are high.

The Low-Intensity Guided Help Through Mindfulness (LIGHTMind) trial tested practitioner-supported MBCT-SH as an alternative.

The findings have “important implications” for the more than 100,000 people currently offered CBT-SH for depression in the Improving Access to Psychological Therapies (IAPT) program each year and in publicly funded services elsewhere, the researchers noted.

If translated into routine practice, “this would see many more people recovering from depression while costing health services less money,” they added.

Lisa McCorkell had a mild bout of COVID-19 in March 2020. Young and healthy, she assumed that she would bounce back quickly. But when her fatigue, shortness of breath, and brain fog persisted, she realized that she most likely had long COVID. 

“Back then, we as patients basically coined the term,” she said. While her first primary care provider was sympathetic, they were unsure how to treat her. After her insurance changed, she ended up with a second primary care provider who didn’t take her symptoms seriously. “They dismissed my complaints and told me they were all in my head. I didn’t seek care for a while after that.”

Ms. McCorkell’s symptoms improved after her first COVID vaccine in the spring of 2021. She also finally found a new primary care doctor she could trust. But as one of the founders of the Patient-Led Research Collaborative, a group of researchers who study long COVID, she said many doctors still don’t know the hallmark symptoms of the condition or how to treat it. 

“There’s still a lack of education on what long COVID is, and the symptoms associated with it,” she said. “Many of the symptoms that occur in long COVID are symptoms of other chronic conditions, such as chronic fatigue syndrome, that are often dismissed. And even if providers believe patients and send them for a workup, many of the routine blood and imaging tests come back normal.”

The term “long COVID” emerged in May 2020. And though the condition was recognized within a few months of the start of the pandemic, doctors weren’t sure how to screen or treat it. 

While knowledge has developed since then, primary care doctors are still in a tough spot. They’re often the first providers that patients turn to when they have symptoms of long COVID. But with no standard diagnostic tests, treatment guidelines, standard care recommendations, and a large range of symptoms the condition can produce, doctors may not know what to look for, nor how to help patients.

“There’s no clear algorithm to pick up long COVID – there are no definite blood tests or biomarkers, or specific things to look for on a physical exam,” said Lawrence Purpura, MD, an infectious disease specialist and director of the long COVID clinic at Columbia University Medical Center, New York. “It’s a complicated disease that can impact every organ system of the body.”

Even so, emerging research has identified a checklist of sorts that doctors should consider when a patient seeks care for what appears to be long COVID. Among them: the key systems and organs impacted by the disease, the most common symptoms, useful therapeutic options for symptom management that have been found to help people with long COVID, and the best healthy lifestyle choices that doctors can recommend to help their patients 

Here’s a closer look at each of these aspects, based on research and interviews with experts, patients, and doctors. 
 

Key systems, organs impacted

About 10% of people who are infected with COVID-19 go on to have long COVID, according to a recent study that Ms. McCorkell helped coauthor. But more than 3 years into the pandemic, much about the condition is still a mystery.

COVID is a unique virus because it can spread far and wide in a patient’s body. A December 2022 study, published in Nature, autopsied 44 people who died of COVID and found that the virus could spread throughout the body and persist, in one case as long as 230 days after symptoms started. 

“We know that there are dozens of symptoms across multiple organ systems,” said Ms. McCorkell. “That makes it harder for a primary care physician to connect the dots and associate it with COVID.”

A paper published in Nature Medicine proposed one way to help guide diagnosis. It divided symptoms into four groups: 

• Cardiac and renal issues such as heart palpitations, chest pain, and kidney damage
• Sleep and anxiety problems like insomnia, waking up in the middle of the night, and anxiety
• In the musculoskeletal and nervous systems: musculoskeletal pain, osteoarthritis, and problems with mental skills
• In the digestive and respiratory systems: trouble breathing, asthma, stomach pain, nausea, and vomiting

There were also specific patterns in these groups. People in the first group were more likely to be older, male, have other conditions and to have been infected during the first wave of the COVID pandemic. People in the second group were over 60% female, and were more likely to have had previous allergies or asthma. The third group was also about 60% female, and many of them already had autoimmune conditions such as rheumatoid arthritis. Members of the fourth group – also 60% female – were the least likely of all the groups to have another condition.

This research is helpful, because it gives doctors a better sense of what conditions might make a patient more likely to get long COVID, as well as specific symptoms to look out for, said Steven Flanagan, MD, a physical medicine and rehabilitation specialist at New York University Langone Medical Center who also specializes in treating patients with long COVID. 

But the “challenge there, though, for health care providers is that not everyone will fall neatly into one of these categories,” he stressed.
 

Checklist of symptoms 

Although long COVID can be confusing, doctors say there are several symptoms that appear consistently that primary care providers should look out for, that could flag long COVID.

Postexertional malaise (PEM). This is different from simply feeling tired. “This term is often conflated with fatigue, but it’s very different,” said David Putrino, PhD, director of rehabilitation innovation at the Mount Sinai Health System in New York, who says that he sees it in about 90% of patients who come to his long COVID clinic. 

PEM is the worsening of symptoms after physical or mental exertion. This usually occurs a day or 2 after the activity, but it can last for days, and sometimes weeks. 

“It’s very different from fatigue, which is just a generalized tiredness, and exercise intolerance, where someone complains of not being able to do their usual workout on the treadmill,” he noted. “People with PEM are able to push through and do what they need to do, and then are hit with symptoms anywhere from 12 to 72 hours later.”

Dysautonomia. This is an umbrella term used to describe a dysfunction of the autonomic nervous system, which regulates bodily functions that you can’t control, like your blood pressure, heart rate, and breathing. This can cause symptoms such as heart palpitations, along with orthostatic intolerance, which means you can’t stand up for long without feeling faint or dizzy. 

“In my practice, about 80% of patients meet criteria for dysautonomia,” said Dr. Putrino. Other research has found that it’s present in about two-thirds of long COVID patients.

One relatively easy way primary care providers can diagnose dysautonomia is to do the tilt table test. This helps check for postural orthostatic tachycardia syndrome (POTS), one of the most common forms of dysautonomia. During this exam, the patient lies flat on a table. As the head of the table is raised to an almost upright position, their heart rate and blood pressure are measured. Signs of POTS include an abnormal heart rate when you’re upright, as well as a worsening of symptoms.

Exercise intolerance. A review published in the journal JAMA Network Open analyzed 38 studies on long COVID and exercise and found that patients with the condition had a much harder time doing physical activity. Exercise capacity was reduced to levels that would be expected about a decade later in life, according to study authors. 

“This is especially important because it can’t be explained just by deconditioning,” said Dr. Purpura. “Sometimes these patients are encouraged to ramp up exercise as a way to help with symptoms, but in these cases, encouraging them to push through can cause postexertional malaise, which sets patients back and delays recovery.”

While long COVID can cause dozens of symptoms, a paper Ms. McCorkell coauthored zeroed in on some of the most common ones: chest pain, heart palpitations, coughing, shortness of breath, belly pain, nausea, problems with mental skills, fatigue, disordered sleep, memory loss, ringing in the ears (tinnitus), erectile dysfunction, irregular menstruation, and worsened premenstrual syndrome.

While most primary care providers are familiar with some of these long COVID symptoms, they may not be aware of others. 

“COVID itself seems to cause hormonal changes that can lead to erection and menstrual cycle problems,” explained Dr. Putrino. “But these may not be picked up in a visit if the patient is complaining of other signs of long COVID.” 

It’s not just what symptoms are, but when they began to occur, he added. “Usually, these symptoms either start with the initial COVID infection, or begin sometime within 3 months after the acute COVID infection. That’s why it’s important for people with COVID to take notice of anything unusual that crops up within a month or 2 after getting sick.”
 

Can you prevent long COVID?

You can’t, but one of the best ways to reduce your risk is to get vaccinated. Getting at least one dose of a COVID vaccine before you test positive for COVID lowers your risk of long COVID by about 35% according to a study published in Antimicrobial Stewardship & Healthcare Epidemiology. Unvaccinated people who recovered from COVID, and then got a vaccine, lowered their own long COVID risk by 27%. 

In addition, a study published in JAMA Internal Medicine found that women who were infected with COVID were less likely to go on to get long COVID and/or have less debilitating symptoms if they had a healthy lifestyle, which included the following: a healthy weight (a body mass index between 18.5 and 24.7 kg/m²), never-smoker, moderate alcohol consumption, a high-quality diet, 7-9 hours of sleep a night, and at least 150 minutes per week of physical activity

But Ms. McCorkell noted that she herself had a healthy preinfection lifestyle but got long COVID anyway, suggesting these approaches don’t work for everyone.

“I think one reason my symptoms weren’t addressed by primary care physicians for so long is because they looked at me and saw that I was young and healthy, so they dismissed my reports as being all in my head,” she explained. “But we know now anyone can get long COVID, regardless of age, health status, or disease severity. That’s why it’s so important that primary care physicians be able to recognize symptoms.”

Lisa McCorkell had a mild bout of COVID-19 in March 2020. Young and healthy, she assumed that she would bounce back quickly. But when her fatigue, shortness of breath, and brain fog persisted, she realized that she most likely had long COVID. 

“Back then, we as patients basically coined the term,” she said. While her first primary care provider was sympathetic, they were unsure how to treat her. After her insurance changed, she ended up with a second primary care provider who didn’t take her symptoms seriously. “They dismissed my complaints and told me they were all in my head. I didn’t seek care for a while after that.”

Ms. McCorkell’s symptoms improved after her first COVID vaccine in the spring of 2021. She also finally found a new primary care doctor she could trust. But as one of the founders of the Patient-Led Research Collaborative, a group of researchers who study long COVID, she said many doctors still don’t know the hallmark symptoms of the condition or how to treat it. 

“There’s still a lack of education on what long COVID is, and the symptoms associated with it,” she said. “Many of the symptoms that occur in long COVID are symptoms of other chronic conditions, such as chronic fatigue syndrome, that are often dismissed. And even if providers believe patients and send them for a workup, many of the routine blood and imaging tests come back normal.”

The term “long COVID” emerged in May 2020. And though the condition was recognized within a few months of the start of the pandemic, doctors weren’t sure how to screen or treat it. 

While knowledge has developed since then, primary care doctors are still in a tough spot. They’re often the first providers that patients turn to when they have symptoms of long COVID. But with no standard diagnostic tests, treatment guidelines, standard care recommendations, and a large range of symptoms the condition can produce, doctors may not know what to look for, nor how to help patients.

“There’s no clear algorithm to pick up long COVID – there are no definite blood tests or biomarkers, or specific things to look for on a physical exam,” said Lawrence Purpura, MD, an infectious disease specialist and director of the long COVID clinic at Columbia University Medical Center, New York. “It’s a complicated disease that can impact every organ system of the body.”

Even so, emerging research has identified a checklist of sorts that doctors should consider when a patient seeks care for what appears to be long COVID. Among them: the key systems and organs impacted by the disease, the most common symptoms, useful therapeutic options for symptom management that have been found to help people with long COVID, and the best healthy lifestyle choices that doctors can recommend to help their patients 

Here’s a closer look at each of these aspects, based on research and interviews with experts, patients, and doctors. 
 

Key systems, organs impacted

About 10% of people who are infected with COVID-19 go on to have long COVID, according to a recent study that Ms. McCorkell helped coauthor. But more than 3 years into the pandemic, much about the condition is still a mystery.

COVID is a unique virus because it can spread far and wide in a patient’s body. A December 2022 study, published in Nature, autopsied 44 people who died of COVID and found that the virus could spread throughout the body and persist, in one case as long as 230 days after symptoms started. 

“We know that there are dozens of symptoms across multiple organ systems,” said Ms. McCorkell. “That makes it harder for a primary care physician to connect the dots and associate it with COVID.”

A paper published in Nature Medicine proposed one way to help guide diagnosis. It divided symptoms into four groups: 

• Cardiac and renal issues such as heart palpitations, chest pain, and kidney damage
• Sleep and anxiety problems like insomnia, waking up in the middle of the night, and anxiety
• In the musculoskeletal and nervous systems: musculoskeletal pain, osteoarthritis, and problems with mental skills
• In the digestive and respiratory systems: trouble breathing, asthma, stomach pain, nausea, and vomiting

There were also specific patterns in these groups. People in the first group were more likely to be older, male, have other conditions and to have been infected during the first wave of the COVID pandemic. People in the second group were over 60% female, and were more likely to have had previous allergies or asthma. The third group was also about 60% female, and many of them already had autoimmune conditions such as rheumatoid arthritis. Members of the fourth group – also 60% female – were the least likely of all the groups to have another condition.

This research is helpful, because it gives doctors a better sense of what conditions might make a patient more likely to get long COVID, as well as specific symptoms to look out for, said Steven Flanagan, MD, a physical medicine and rehabilitation specialist at New York University Langone Medical Center who also specializes in treating patients with long COVID. 

But the “challenge there, though, for health care providers is that not everyone will fall neatly into one of these categories,” he stressed.
 

Checklist of symptoms 

Although long COVID can be confusing, doctors say there are several symptoms that appear consistently that primary care providers should look out for, that could flag long COVID.

Postexertional malaise (PEM). This is different from simply feeling tired. “This term is often conflated with fatigue, but it’s very different,” said David Putrino, PhD, director of rehabilitation innovation at the Mount Sinai Health System in New York, who says that he sees it in about 90% of patients who come to his long COVID clinic. 

PEM is the worsening of symptoms after physical or mental exertion. This usually occurs a day or 2 after the activity, but it can last for days, and sometimes weeks. 

“It’s very different from fatigue, which is just a generalized tiredness, and exercise intolerance, where someone complains of not being able to do their usual workout on the treadmill,” he noted. “People with PEM are able to push through and do what they need to do, and then are hit with symptoms anywhere from 12 to 72 hours later.”

Dysautonomia. This is an umbrella term used to describe a dysfunction of the autonomic nervous system, which regulates bodily functions that you can’t control, like your blood pressure, heart rate, and breathing. This can cause symptoms such as heart palpitations, along with orthostatic intolerance, which means you can’t stand up for long without feeling faint or dizzy. 

“In my practice, about 80% of patients meet criteria for dysautonomia,” said Dr. Putrino. Other research has found that it’s present in about two-thirds of long COVID patients.

One relatively easy way primary care providers can diagnose dysautonomia is to do the tilt table test. This helps check for postural orthostatic tachycardia syndrome (POTS), one of the most common forms of dysautonomia. During this exam, the patient lies flat on a table. As the head of the table is raised to an almost upright position, their heart rate and blood pressure are measured. Signs of POTS include an abnormal heart rate when you’re upright, as well as a worsening of symptoms.

Exercise intolerance. A review published in the journal JAMA Network Open analyzed 38 studies on long COVID and exercise and found that patients with the condition had a much harder time doing physical activity. Exercise capacity was reduced to levels that would be expected about a decade later in life, according to study authors. 

“This is especially important because it can’t be explained just by deconditioning,” said Dr. Purpura. “Sometimes these patients are encouraged to ramp up exercise as a way to help with symptoms, but in these cases, encouraging them to push through can cause postexertional malaise, which sets patients back and delays recovery.”

While long COVID can cause dozens of symptoms, a paper Ms. McCorkell coauthored zeroed in on some of the most common ones: chest pain, heart palpitations, coughing, shortness of breath, belly pain, nausea, problems with mental skills, fatigue, disordered sleep, memory loss, ringing in the ears (tinnitus), erectile dysfunction, irregular menstruation, and worsened premenstrual syndrome.

While most primary care providers are familiar with some of these long COVID symptoms, they may not be aware of others. 

“COVID itself seems to cause hormonal changes that can lead to erection and menstrual cycle problems,” explained Dr. Putrino. “But these may not be picked up in a visit if the patient is complaining of other signs of long COVID.” 

It’s not just what symptoms are, but when they began to occur, he added. “Usually, these symptoms either start with the initial COVID infection, or begin sometime within 3 months after the acute COVID infection. That’s why it’s important for people with COVID to take notice of anything unusual that crops up within a month or 2 after getting sick.”
 

Can you prevent long COVID?

You can’t, but one of the best ways to reduce your risk is to get vaccinated. Getting at least one dose of a COVID vaccine before you test positive for COVID lowers your risk of long COVID by about 35% according to a study published in Antimicrobial Stewardship & Healthcare Epidemiology. Unvaccinated people who recovered from COVID, and then got a vaccine, lowered their own long COVID risk by 27%. 

In addition, a study published in JAMA Internal Medicine found that women who were infected with COVID were less likely to go on to get long COVID and/or have less debilitating symptoms if they had a healthy lifestyle, which included the following: a healthy weight (a body mass index between 18.5 and 24.7 kg/m²), never-smoker, moderate alcohol consumption, a high-quality diet, 7-9 hours of sleep a night, and at least 150 minutes per week of physical activity

But Ms. McCorkell noted that she herself had a healthy preinfection lifestyle but got long COVID anyway, suggesting these approaches don’t work for everyone.

“I think one reason my symptoms weren’t addressed by primary care physicians for so long is because they looked at me and saw that I was young and healthy, so they dismissed my reports as being all in my head,” she explained. “But we know now anyone can get long COVID, regardless of age, health status, or disease severity. That’s why it’s so important that primary care physicians be able to recognize symptoms.”

The youngest patient with cannabis-induced psychosis (CIP) whom Karen Randall, DO, has treated was a 7-year-old boy. She remembers the screaming, the yelling, the uncontrollable rage.

Dr. Randall is an emergency medicine physician at Southern Colorado Emergency Medicine Associates, a group practice in Pueblo, Colo. She treats youth for cannabis-related medical problems in the emergency department an average of two or three times per shift, she said.

Colorado legalized the recreational use of cannabis for adults older than 21 in 2012. Since then, Dr. Randall said, she has noticed an uptick in cannabis use among youth, as well as an increase in CIP, a syndrome that can be indistinguishable from other psychiatric disorders such as schizophrenia in the emergency department. But the two conditions require different approaches to care.

“You can’t differentiate unless you know the patient,” Dr. Randall said in an interview.

In 2019, 37% of high school students in the United States reported ever using marijuana, and 22% reported use in the past 30 days. Rates remained steady in 2020 following increases in 2018 and 2019, according to the Centers for Disease Control and Prevention.

The CDC also found that 8% of 8th graders, 19% of 10th graders, and 22% of 12th graders reported vaping marijuana in the past year.

Clinicians in states where recreational marijuana has been legalized say they have noticed an increase in young patients with psychiatric problems – especially after consumption of cannabis products in high doses. But CIP can be tricky to distinguish from psychoses of other causes, such as schizophrenia or bipolar disorder, which often begin to present in adolescence.
 

How to differentiate

CIP is characterized by delusions and hallucinations and sometimes anxiety, disorganized thoughts, paranoia, dissociation, and changes in mood and behavior. Symptoms typically last for a couple hours and do not require specific treatment, although they can persist, depending on a patient’s tolerance and the dose of tetrahydrocannabinol (THC) they have consumed. Research suggests that the higher the dose and concentration of the drug consumed, the more likely a person will develop symptoms of psychosis.

Diagnosis requires gathering information on previous bipolar disorder or schizophrenia diagnosis, prescriptions for mental illness indications, whether there is a family history of mental illness, and whether the patient recently started using marijuana. In some cases, marijuana use might exacerbate or unmask mental illness.

If symptoms of CIP resolve, and usually they do, clinicians can recommend that patients abstain from cannabis going forward, and psychosis would not need further treatment, according to Divya Singh, MD, a psychiatrist at Banner Behavioral Health Hospital in Scottsdale, Ariz., where recreational cannabis became legal in 2020.

“When I have limited information, especially in the first couple of days, I err on the side of safety,” Dr. Singh said.

Psychosis is the combination of symptoms, including delusions, hallucinations, and disorganized behavior, but it is not a disorder in itself. Rather, it is the primary symptom of schizophrenia and other chronic psychiatric illnesses.

Schizophrenia can be diagnosed only after a patient presents with signs of disturbance for at least 6 months, according to guidelines in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Dr. Singh said a diagnosis of schizophrenia cannot be made in a one-off interaction.

If the patient is younger than 24 years and has no family history of mental illness, a full recovery is likely if the patient abstains from marijuana, he said. But if the patient does have a family history, “the chances of them having a full-blown mental illness is very high,” Dr. Singh said.

If a patient reports that he or she has recently started using marijuana and was previously diagnosed with bipolar disorder or schizophrenia, Dr. Singh said he generally prescribes medications such as lithium or quetiapine and refers the patient to services such as cognitive-behavioral therapy. He also advises against continuing use of cannabis.

“Cannabis can result in people requiring a higher dose of medication than they took before,” Dr. Singh said. “If they were stable on 600 mg of lithium before, they might need more and may never be able to lower the dose in some cases, even after the acute episode.”
 

The science of cannabis

As of March 2023, 21 states and the District of Columbia permit the recreational use of marijuana, according to the Congressional Research Service. Thirty-seven states and the District of Columbia allow medicinal use of marijuana, and 10 states allow “limited access to medical cannabis,” defined as low-THC cannabis or cannabidiol (CBD) oil.

THC is the main psychoactive compound in cannabis. It creates a high feeling after binding with receptors in the brain that control pain and mood. CBD is another chemical found in cannabis, but it does not create a high.

Some research suggests cannabinoids may help reduce anxiety, reduce inflammation, relieve pain, control nausea, reduce cancer cells, slow the growth of tumor cells, relax tight muscles, and stimulate appetite.

The drug also carries risks, according to Mayo Clinic. Use of marijuana is linked to mental health problems in teens and adults, such as depression, social anxiety, and temporary psychosis, and long-lasting mental disorders, such as schizophrenia.

In the worst cases, CIP can persist for weeks or months – long after a negative drug test – and sometimes does not subside at all, according to Ken Finn, MD, president and founder of Springs Rehabilitation, PC, a pain medicine practice in Colorado Springs, Colo.

Dr. Finn, the co–vice president of the International Academy on the Science and Impact of Cannabis, which opposes making the drug more accessible, said educating health care providers is an urgent need.

Studies are mixed on whether the legalization of cannabis has led to more cases of CIP.

A 2021 study found that experiences of psychosis among users of cannabis jumped 2.5-fold between 2001 and 2013. But a study published earlier this year of more than 63 million medical claims from 2003 to 2017 found no statistically significant difference in rates of psychosis-related diagnoses or prescribed antipsychotics in states that have legalized medical or recreational cannabis compared with states where cannabis is still illegal. However, a secondary analysis did find that rates of psychosis-related diagnoses increased significantly among men, people aged 55-64 years, and Asian adults in states where recreational marijuana has been legalized.

Complicating matters, researchers say, is the question of causality. Cannabis may exacerbate or trigger psychosis, but people with an underlying psychological illness may also be more likely to use cannabis.

Dr. Finn said clinicians in Colorado and other states with legalization laws are seeing more patients with CIP. As more states consider legalizing recreational marijuana, he expects the data will reflect what doctors experience on the ground.

Cannabis-induced “psychosis is complicated and likely underdiagnosed,” Dr. Finn said.
 

Talking to teens

Clinicians outside the emergency department can play a role in aiding young people at risk for CIP. Primary care physicians, for instance, might explain to young patients that the brain only becomes fully developed at roughly age 26, after which the long-term health consequences of using cannabis become less likely. According to the CDC, using cannabis before age 18 can change how the brain builds connections and can impair attention, memory, and learning.

Dr. Singh takes a harm reduction approach when he engages with a patient who is forthcoming about substance use.

“If I see an 18-year-old, I tell them to abstain,” he said. “I tell them if they are ever going to use it, to use it after 26.”

Clinicians also should understand dosages to provide the optimal guidance to their patients who use cannabis.

“People often have no idea how much cannabis they are taking,” especially when using vape cartridges, Dr. Singh said. “If you don’t know, you can’t tell patients about the harms – and if you tell them the wrong information, they will write you off.”

Dr. Singh said he advises his patients to avoid using cannabis vapes or dabbing pens. Both can contain much higher levels of THC than dried flower or edible forms of the drug. He also says patients should stick with low concentrations and use products that contain CBD, which some studies have shown has a protective effect against CIP, although other studies have found that CBD can induce anxiety.

He also tells patients to buy from legal dispensaries and to avoid buying street products that may have methamphetamine or fentanyl mixed in.

Despite the risks, Dr. Singh said legalization can reduce the stigma associated with cannabis use and may prompt patients to be honest with their clinicians. Dr. Singh recalled a 28-year-old patient who was using cannabis to alleviate her arthritic pain. She also was taking a transplant medication, which carried potential side effects of delirium, generalized anxiety disorder, and hallucinosis. After doubling her THC dose, the patient experienced severe anxiety and paranoia.

Dr. Singh’s patient paid him a visit and asked for help. Dr. Singh told her to reduce the dose and to keep track of how she felt. If she continued to feel anxious and paranoid, he recommended that she switch to CBD instead.

“I think education and knowledge is liberating,” Dr. Singh said. “Legalization and frank conversations help people understand how to use a product – and right now, I think that’s lacking.”

According to the CDC, using cannabis before age 18 can change how the brain builds connections and can impair attention, memory, and learning.

Dr. Singh takes a harm reduction approach when he engages with a patient who is forthcoming about substance use.

“If I see an 18-year-old, I tell them to abstain,” he said. “I tell them if they are ever going to use it, to use it after 26.”

Clinicians also should understand dosages to provide the optimal guidance to their patients who use cannabis.

“People often have no idea how much cannabis they are taking,” especially when using vape cartridges, Dr. Singh said. “If you don’t know, you can’t tell patients about the harms – and if you tell them the wrong information, they will write you off.”

Dr. Singh said he advises his patients to avoid using cannabis vapes or dabbing pens. Both can contain much higher levels of THC than dried flower or edible forms of the drug. He also says patients should stick with low concentrations and use products that contain CBD, which some studies have shown has a protective effect against CIP, although other studies have found that CBD can induce anxiety.

He also tells patients to buy from legal dispensaries and to avoid buying street products that may have methamphetamine or fentanyl mixed in.

Despite the risks, Dr. Singh said legalization can reduce the stigma associated with cannabis use and may prompt patients to be honest with their clinicians. Dr. Singh recalled a 28-year-old patient who was using cannabis to alleviate her arthritic pain. She also was taking a transplant medication, which carried potential side effects of delirium, generalized anxiety disorder, and hallucinosis. After doubling her THC dose, the patient experienced severe anxiety and paranoia.

Dr. Singh’s patient paid him a visit and asked for help. Dr. Singh told her to reduce the dose and to keep track of how she felt. If she continued to feel anxious and paranoid, he recommended that she switch to CBD instead.

“I think education and knowledge is liberating,” Dr. Singh said. “Legalization and frank conversations help people understand how to use a product – and right now, I think that’s lacking.”

The antipsychotic clozapine appears to guard against suicide for patients with treatment-resistant schizophrenia, results of an autopsy study suggest.

Investigators reviewed over 53,000 autopsy records, including over 600 from individuals whose autopsies revealed the presence of the antipsychotics clozapine or olanzapine, and found that those who took clozapine were significantly less likely to have died by suicide, compared with their counterparts who were taking olanzapine.

“Clozapine is an important and effective antisuicide medicine and should be strongly considered for treatment-resistant psychotic disorders, especially when the patient may be at risk for suicide,” study investigator Paul Nestadt, MD, associate professor, department of psychiatry and behavioral sciences, Johns Hopkins School of Medicine, Baltimore, told this news organization.

The study was published online in The Journal of Clinical Psychiatry.
 

Underutilized medication

Clozapine is the only medication indicated for treatment-resistant schizophrenia and is considered “the most efficacious antipsychotic,” the investigators note. Unfortunately, it has “long been underutilized” for several reasons, including prescriber hesitancy and concerns about side effects.

The authors note that its mechanism of action and the basis for superior efficacy are “still poorly understood” but “may extend beyond neurotransmitter receptor binding.”

Importantly, it may have a beneficial impact on domains other than positive symptoms of schizophrenia, including suicidality. Several studies have shown that it’s beneficial in this regard, but it is “unclear whether the unique antisuicidal properties of clozapine are related to better symptom control ... or to the closer monitoring and follow-up mandated for clozapine use,” they note.

A previous trial, the International Suicide Prevention Trial (InterSePT), demonstrated that clozapine is associated with a greater reduction in suicidality, and the findings “led to an FDA indication for clozapine in reducing the risk of recurrent suicidal behavior.”

However, the authors note, “in the severely ill populations in these studies, it is difficult to be certain about patients’ adherence to prescribed clozapine.”

“Other studies, such as InterSePT, have shown some evidence of clozapine working to reduce suicide-related outcomes, such as attempts or suicidal ideation, but few have been sufficiently powered to measure an effect on actual suicide deaths,” said Dr. Nestadt.

‘Untapped resource’

Of 53,133 decedents, olanzapine or clozapine was detected in the blood of 621 persons (n = 571 and n = 50, respectively).

There were no significant differences in age, sex, race, or urban residence between the decedents who were treated with olanzapine and those who received clozapine.

The odds of a death by suicide in those treated with clozapine were less than half of the odds among decedents who had been treated with olanzapine (odds ratio, 0.47; 95% confidence interval, 0.26-0.84; P = .011).

In sensitivity analyses, the investigators reanalyzed the data to compare clozapine with other antipsychotics, including chlorpromazine, thioridazine, quetiapine, and olanzapine, and the results were similar. The odds of suicide (compared with accident) in those taking clozapine were much lower than in those taking any other tested antipsychotics individually or in combination (OR, 0.42; 95% CI, 0.24-0.73; P = .002).

Dr. Nestadt outlined several hypotheses regarding the mechanism of clozapine’s antisuicidal properties.

“Most theories stem from the differences in its receptor affinity, compared [with] the other neuroleptics,” he said. “In addition to the more typical dopaminergic blockade seen in neuroleptics, clozapine enhances serotonin release and greatly increases peripheral norepinephrine.”

This has been shown to “grant clozapine a greater antidepressant effect than other neuroleptics while also potentially decreasing aggression and impulsivity, which are both strongly associated with suicide risk,” he said.

Clozapine may also “work to reduce the inflammation-triggered activation of the kynurenine pathway, which otherwise contributes to serotonin depletion,” he added.

He noted that some studies have shown that as many as 1 in 10 patients with schizophrenia die by suicide, “so addressing this risk is paramount,” and that clozapine can play an important role in this.

The authors note that the findings “also highlight the utility of state-wide autopsy records, an untapped resource for investigating the potential protective effect of psychiatric medications on suicide at a population level.

“Importantly, we can be certain that this was not an issue of nonadherence to treatment in either group, which is a common issue in the use of these drugs because, instead of prescription records or self-report, we used actual measurements of drug presence in decedents’ blood at death,” said Dr. Nestadt.
 

‘Strongly suggestive’ data

Commenting on the study, Maria Oquendo, MD, PhD, Ruth Meltzer Professor and chair of psychiatry, Perelman School of Medicine, University of Pennsylvania, Philadelphia, said most work on antisuicidal psychopharmacologic approaches “focuses on suicidal ideation or suicide attempts, due to the rarity of suicide death, even in high-risk populations.”

“Showing that clozapine may decrease risk for the most dreaded outcome of schizophrenia – suicide – is critically important,” said Dr. Oquendo, past president of the American Psychiatric Association.

Nevertheless, some questions remain, said Dr. Oquendo, who was not involved with the study. “Comparison of suicides to only accidental deaths has limitations. Many individuals who die due to accidents, like many suicides, are not similar to the general population,” she added.

However, she acknowledged, the data are strongly suggestive that clozapine protects against suicide.

“While not definitive, ideally these findings will stimulate changes in prescribing practices which may be lifesaving both literally – in terms of preventing suicides – and figuratively, given the drug’s effect on symptoms that impact quality of life and functioning,” said Dr. Oquendo.

The study received no funding or support. Dr. Nestadt is supported by the American Foundation for Suicide prevention and the National Institute on Drug Abuse. The other authors’ disclosures are listed in the original article.

A 2.5-mg dose of olanzapine once daily significantly improved appetite in patients undergoing chemotherapy for locally advanced or metastatic gastric, hepatopancreaticobiliary, or lung cancer.

Anorexia is a problem in approximately 50% of newly-diagnosed cancer patients, and can compromise survival, wrote study author Lakshmi Sandhya, MD, of Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, India, and colleagues. In particular, patients with lung and gastrointestinal tract cancers are prone to anorexia during chemotherapy, they said. Olanzapine is a demonstrated appetite stimulant and has been used in cancer patients as a short-term antiemetic, but its use for long-term appetite stimulation has not been well-studied, they said.

In the study, published in the Journal of Clinical Oncology, the researchers randomized 124 adults aged 18 years and older to a 2.5 grams of olanzapine or placebo for 12 weeks. The participants had untreated, locally advanced, or metastatic gastric, hepatopancreaticobiliary (HPB), or lung cancers.

The median age of the participants was 55 years. The primary outcome was a weight gain greater than 5% and improved appetite based on the visual analog scale (VAS) and questionnaires. A change in nutritional status, quality of life (QOL), and chemotherapy toxicity, were secondary endpoints.

After 12 weeks, complete data were available for 58 patients in the olanzapine group and 54 in the placebo group. Of these, 60% of the olanzapine group and 9% of the placebo group met the primary endpoint of a weight gain greater than 5%. The proportion of patients with improved appetite based on VAS scores and questionnaire scores was significantly higher in olanzapine patients vs. placebo patients (43% vs. 13% and 22% vs. 4%, respectively).

In addition, 52% of the olanzapine group vs. 18% of the placebo group achieved more than 75% intake of recommended daily calories.

Most of the reported toxicities were not hematological and similar between the groups (85% for olanzapine vs. 88% for placebo). The proportion of patients with toxicities of grade 3 or higher was lower in the olanzapine group vs. the placebo group (12% vs. 37%, P = .002). Patients in the olanzapine group also reported significantly improved quality of life from baseline compared to the placebo patients.

The findings were limited by several factors including the heterogeneous cancers and treatment regimens, the lack of data on weight beyond 12 weeks, the relatively small study population, and the subjective nature of anorexia measurements, the researchers noted.

However, the results suggest that low-dose olanzapine is an effective and well-tolerated add-on intervention for the subset of patients at risk for anorexia at the start of chemotherapy, they said.

“Future studies could look at various cancers in a multicentric setting and long-term endpoints such as patient survival,” they concluded.

The study drug and placebo were funded by an intramural grant from Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER). The researchers had no financial conflicts to disclose.
